OBD II Drive Cycle

All kinds of diagnostic trouble codes (DTCs) can be monitored by carrying out a test drive according to the following six drive cycle pattern. In other words doing such a drive regenerates any kind of trouble which involves illuminating the Malfunction Indicator Lamp (SERVICE ENGINE SOON) and verifies the repair procedure has eliminated the trouble (the Malfunction Indicator Lamp (SERVICE ENGINE SOON) is no longer illuminated).

CAUTION: Two technicians should always be in the vehicle when carrying out a test drive.

NOTE: Check that the diagnosis trouble code (DTC) is not output before traveling in the drive cycle pattern. Era se the DTC if it has been output.
